how can i add a layer to my current image in script-fu?

(NewLayer (car (gimp-layer-new Image yourwidth yourheight RGB "new" 100 NORMAL)))
(gimp-image-add-layer Image NewLayer -1)

Image=the name of your current image

where do i find my image name?

Image is NOT the name of the image. It is an ID number.

@croccaroc96

How are you running your script: From a menu or from the command line?

If from a menu, then your script will be passed the ID number of the image if you have defined a SF-IMAGE parameter in the registration.

If from the command line then your script will have to load the image using something like gimp-file-load which will return the ID number.

ok thank you kevin in this moment i'm scripting with the console but later i will save it and run it by the menu

In Python:


If this is a script that you add in a menu, it will typically take at least one argument, which is set by Gimp to the current image, and a very often a second one which is filled with the current layer.

On the python console, if you have one single image.


If you have several images but you know the name of the one you want:

Yes, Kevin. A typo

my script (not working):

(define (script-fu-practise-myscript image Drawable) (let* ( (theImageWidth 1280) (theImageHeight 768) (layer (car (gimp-layer-new image theImageWidth theImageHeight 2 "nero" 100 4) ) ) ) (gimp-image-add-layer image layer 0) (gimp-context-set-background '(0 0 0) ) (gimp-context-set-foreground '(255 255 255) ) (gimp-drawable-fill layer BACKGROUND-FILL) (plug-in-grid 0 image layer 2 8 0 '(255 255 255) 100 2 8 0 '(255 255 255) 100 2 8 0 '(255 255 255) 100) (plug-in-gauss 0 image layer 8 8 1) (let* ( (visible (car (gimp-layer-new-from-visible image image "visible")))) (gimp-image-add-layer image visible 0)(plug-in-c-astretch 0 image visible))))

One can obtain the ID number of an already loaded image by opening the "Image->Canvas size..." dialog and noting the number that follows the hyphen in the image name at the very top. After you have noted the ID, close the dialog with the Cancel button. (A similar approach will work for layers, channels, and paths -- just find a suitable dialog.)

When I run your code I get the following error message:

What type of image are you starting with? RGB/Greyscale/Indexed? as you have created a new layer with mode 2 = Grayscale (better if you use the predefined constants: GRAY-IMAGE etc) but then tried to add it to an RGB image.

ok new code working:



the nuber 1 stay for the image id. now i need to put this script in the script-fu menu and i need to auto-identify the image id. can someone help me?

See my example of your code where I added the menu registration: viewtopic.php?f=9&t=10697#p141676

Kevin

i need to edit something? because it gives me an error while trying to reload scripts

this is right?

it now looks like this:

script:

You are missing a parenthesis. try this:


Kevin

no errors now. in which menu i find it?

omg *facepalm* sorry for the question XD

Remember that question when you write a script for someone else and give them the answer before they ask.

Kevin

thanks to all now it works

special thanks to kevin
